Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a high-efficiency energy-saving anaerobic reactor for urban sewage treatment. Background Art

[0002] In the process of urban sewage treatment, anaerobic reactors are needed to treat organic pollutants in sewage and industrial wastewater. The principle is based on the metabolism of anaerobic microorganisms under anaerobic or anoxic conditions. Under anaerobic conditions, complex organic substances in sewage (such as carbohydrates, proteins, fats, etc.) will be gradually decomposed into simpler substances by microorganisms. In application, after the sewage is introduced into the anaerobic reactor, the inoculated sludge containing rich microbial communities needs to be introduced into the anaerobic reactor so that the sludge can be mixed with the sewage, so that the microorganisms in the sludge react with the organic matter in the sewage. In order to improve the mixing efficiency of sludge and sewage, the mixture of sludge and sewage is stirred by a stirring rod inside the reactor. However, in the actual operation process, when the sludge is introduced into the reactor, it will be in a relatively large aggregated mass. Although the aggregated sludge can be broken up by stirring, the density of the sludge itself is greater than that of the sewage, causing it to gradually settle under the action of gravity, and through its own viscosity, it will contact with other sludge particles and aggregate again, thereby reducing the contact opportunity between sewage and sludge, and reducing the efficiency of sewage treatment.

The sewage and sludge entering the interior of the operation chamber 1 will be located above the lifting plate 3. A driving motor 11 is provided at the bottom of the operation chamber 1. The output end of the driving motor 11 is connected to the transmission seat 13. An extension rod 14 slides inside the transmission seat 13, so that the driving motor 11 can drive the transmission seat 13 and the extension rod 14 to rotate, and the extension rod 14 is fixed to the driven rod 32, so that the driving motor 11 can drive the driven rod 32 to rotate, and a plurality of stirring rods 32 are fixed to the outside of the driven rod 32. 1, so that the driven rod 32 will drive the stirring rod 321 to move synchronously when it rotates, and the stirring rod 321 will stir the sewage and the sludge when it rotates, so that the sewage can keep in a flowing state, so that the sewage and the sludge can contact each other, and a hydraulic rod is installed at the bottom end of the lifting plate 3, so that the lifting plate 3 can move vertically inside the working chamber 1, and the extension rod 14 can slide inside the transmission seat 13, so that the extension rod 14 can move vertically, thereby avoiding obstruction to the vertical movement of the lifting plate 3, and because the sludge is located above the lifting plate 3, the lifting plate 3 will drive the sludge to move synchronously when it moves, and an extrusion hole 31 is opened inside the lifting plate 3, and the sewage and granular sludge smaller than the extrusion hole 31 will pass through the extrusion hole 31 through the lifting plate The lifting plate 3 moves upward and the sludge is fully contacted with the sewage during the sedimentation process. The lifting plate 3 can also fully contact with the sewage when driving the sludge to move upward. When the lifting plate 3 moves vertically, the contact block 322 fixed on the top of the driven rod 32 will first contact the interlocking plate 21 and drive the interlocking plate 21 to move vertically upward, so as to avoid the driven rod 32 from hindering the vertical movement of the lifting plate 3. The stirring rod 321 can throw out the sludge through the centrifugal force when rotating, so as to avoid the sludge being near the driven rod 32. When the lifting plate 3 drives the sludge to contact the bottom end of the squeezing plate 2, the sludge will be squeezed by the squeezing plate 2 and the lifting plate 3, so that the sludge will be squeezed into the extrusion hole 31, and then the sludge will be divided into a plurality of particles by the extrusion hole 31. The granular sludge settles downward, so that the sludge can fully contact and react with the sewage, thereby improving the efficiency of sewage treatment and the utilization rate of the sludge, and achieving the purpose of energy saving.
